Description

FEMALE: (n = 8) Body fusiform, 191 (185–195) long, 61 (60–63) wide, 60 (57–61) thick; light yellow. Gnathosoma 26 (24–28), projecting obliquely down. Prodorsal shield 42 (42–43) long, 64 (62–66) wide; semicircular; frontal lobe present; median, admedian and submedian lines present, obscure. Scapular tubercles on rear margin, 41 (39–42) apart, scapular setae (sc) 12 (12–13) projecting posterior. Coxal area with short lines; anterolateral setae on coxisternum (1b) 7 (6–9), proximal setae on coxisternum (1a) 16 (15–19), proximal setae on coxisternum (2a) 46 (43–51). Prosternal apodeme present. Legs with usual series of setae. Legs 29 (27–31), femur 9 (9–10), basiventral femoral setae (bv) 11 (10–14); genu 5 (5–6), antaxial genual setae (l'') 18 (17–19); tibia 8 (8–9), paraxial tibial setae (l') 6 (5–6), setae located 1/3 from dorsal base; tarsus 5 (5–6); tarsal empodium simple, 4­rayed, tarsal solenidion knobbed. Legs 25 (23–27), femur 7 (6–8), basiventral femoral setae (bv) 11 (10–11); genu 4 (4–5), antaxial genual setae (l'') 10 (9–11); tibia 6 (6–7); tarsus 5 (5–6); tarsal empodium simple, 4­rayed, tarsal solenidion knobbed. Opisthosoma: dorsal opisthosoma with 29 (28–31) annuli, with elliptical microtubercles, ventrally with 56 (54–57) microtuberculate annuli. Setae c2 29 (28–33) on ventral annulus 12 (11–12); setae d 40 (38–42) on ventral annulus 23 (22–24); setae e 28 (26–31) on ventral annulus 39 (38–41), setae f 40 (38–42) on 6th ventral annulus from rear. Setae h1 4 (3–4). Female genitalia 15 (14–16) long, 21 (21–22) wide, coverflap with 10 longitudinal ridges and 2 transverse lines at base, proximal setae on coxisternum (3a) 13 (12–15).

MALE: Unknown.

Types

Holotype, female, China : Shaanxi Province, Cuihua Mountain, 32°59.40’N, 109°00.04’E. August 14, 2005, from Populus sp. L. ( Salicaceae ), coll. Xue, Xiao­Feng & Song, Zi­Wei. Paratypes, 7 females, with the same data as holotype.

Relation to host

Mites are vagrant on leaf surface, causing no apparent damage.

Remarks

This species is similar to Tetra populi Kuang, Kuang & Zhang, 1999 , but can be differentiated by prodorsal shield with median, admedian and submedian lines present and obscure (only with admedian lines in T. populi ), opisthosoma with microtubercles on dorsal annuli (dorsal annuli smooth in T. populi ) and female genital coverflap with 10 longitudinal ridges and 2 transverse lines at base (female genital coverflap with 12 to 14 longitudinal ridges in T. populi ).
